"a reason to decline taking a free-speech case “the extent to which the speech may assist in advancing the goals of white supremacists or others whose views are contrary to our values." In selecting speech cases to defend, the ACLU will now balance the “impact of the proposed speech and the impact of its suppression.” Factors like the potential effect of the speech on “marginalized communities” and even on “the ACLU’s credibility” could militate against taking a case."

Your list looks impressive. But what cases did they choose to not accept that aren't listed there?
Now it apparently means "subscribes to currently trendy theories of social justice."
However, that was a very specific and rather recent change. ACLU before that change can still be seen as a model organization that threw its weight behind causes regardless of whether they were "left wing" or "right wing", so long as one of its principles were affected.
